Laparoscopic gastric bypass at a large academic medical center: lessons learned from the first 1000 cases.
Bariatric surgery is an effective and durable treatment for morbid obesity in properly selected patients. Surgical outcomes and patient management methods should routinely be reviewed to improve patient care and maintain long-term effectiveness of the bariatric operation. Over a 5-year period, 1096 laparoscopic Roux-en-Y gastric bypass operations were performed at our institution. A comprehensive prospective database was maintained, which included data for comorbidities, operative techniques, perioperative management, complications, and follow up. Many practice patterns such as the omission of routine preoperative sleep apnea testing and biliary ultrasounds remained constant and were validated by the outcomes measured. Several changes, however, were implemented based on outcomes analyses, including antecolic placement of the roux limb, a pars flaccida approach to the creation of the gastric pouch, longer alimentary limbs in superobese patients, and a selective approach to postoperative upper gastrointestinal imaging. Postoperative weight regain and inability to maintain long-term follow up in a significant per cent of patients were two identified and ongoing problems. Maintenance of a bariatric patient database is essential with its routine review resulting in changes to practice patterns and operative techniques. An effective method for long-term patient follow up remains elusive and may contribute to postoperative weight regain in some patients.
